6 Claims.

. This invention relates to window constructions, P rticularly to windows for use in motor vehicles, railway cars, airships, etc. It has for its object a window construction in which the glass pane is cushioned throughout its entire circumference against strains, shocks and jars and to internal strains due to expansion and contraction under varied degrees of temperature.

It further has for its object a window conn struction in which the resilient mounting or resilient sash frame for the glass pane is clamped or compressed on the margins of the glass pane, so that the resilient mounting or sash frame not only cushions the glass pane throughout its enlo tire circumference against strains, shocks, etc., but also resiliently but snugly holds the glass in the mounting of the glass frame.

It further has for its object a window construction in which the mounting or sash frame in its entirety is an elastic and compressible or resilient tirelike member having a groove for receiving the margin of the glass pane, with the greater part of said member located beyond the edge of theglass pane and the mounting located in a channel in an outside holding means or frame, which channel has means operable to compress the mounting against the walls of the channel and against opposite sides of the margin.

of the glass pane.

It further has for its object an elastic and compressible or resilient mounting for the glass pane which is under tension when applied to the glass pane and also under compression, when the sash, including the glass pane and its mounting, is mounted in the channel on an outside or holding frame.

It further has for its object a double sash, each including a compressible mounting or sash frame directly receiving the margin of the glass pane and coacting directly with the walls ofthe channel of the supporting or outside frame, the double sash being so mounted in the-channel that when compressed 'in the channel, the mountings of each compresses against each other and also against the sides and bottom of the channel.

It further has for its object means compressible between the mountings of the two sashes for dehydrating the air between the sashes.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding parts in all l the views.

Figure 1 is a fragmentary elevation of a double sash window embodying this invention.

Figure 2 is a sectional view on line 22, Figure 3.

- Figure 3 is a fragmentary sectional view on line 3-4, Figure l.

Figure 4 is an elevation on a reduced scale i1- lustrating the continuity of the elastic and compressible mounting or sash frame.

' Figure 5 is a view similar to Figure 2 illustrating a single sash window embodying this invention.

The window is designed to be fixedly mounted, that is, to have no opening and closing movement.

I designates the glass pane and 2 the mounting for the glass pane which may be considered a sash frame, as distinguished from a rubber channel, serving as a seat for the margin of the glass pane, and mounted in the channel of a sash frame of wood or metal, which in turn is mounted in a window frame.

3 designates the outside or window frame formed with a channel 4 for receiving the mounting'or mountings 2, the window frame having one side 5 of the channel removable and operable to have a clamping or compressing action against the mounting or mountings 2.

The mounting 2 is a tirelike member, which entirely surrounds the periphery of the glass pane i and is provided with a groove ,6 for receiving the margin of the glass pane, the greater part I of the mounting being located beyond the edge of the glass pane l. The mounting is elastic and compressible, and usually of rubber or some form of sponge rubber. It is in the form of an endless belt and initially is of less length circumferentially than the edge of the glass pane I, so

that it is stretched when placed on the glass pane, and hence, under tension, when in position on the glass pane. Preferably, the glass pane has rounding corners, as seen in Figure 1, and consequently the elastic compressible mounting 2 is rounding at the corners, and likewise the channel 4 of the outside frame 3 is rounding. This outside frame is usually the window frame set directly into the window opening of the body of the vehicle or other structure to which the Window is applied. The frame 3 is formed of metal and the channel is here, shown as substantially rectangular in general form in cross section with one side 5 thereof removable and clamped in position, as by screws 8. Also, the cross sectional shape of the member 2 is different from that of the channel, and in order to permit distortion ofthe member 2, when compressed, and during such distortion to press against the sides and bottom of the channel, and

in a double sash, also against the mounting of the other glass pane.

As here illustrated, the outer comers of the members 2 instead of being square are removed, so that the outer periphery of the member 2 is semioctagonal.

In Figure 2, wherein a double sash is shown, the bottom of the channel is formed with a rib 9, which extends part way.between the bodies 2 of the double sash and serves as a shoulder for preventing unintentional displacement of the sash, the rubber mounting 2 of which is located against the fixed side of the channel 4, that is, the side opposed to the removable side 5. In placing the sash with its mounting 2 in the channel against the fixed side of the channel, the mounting 2 is compressed at some points sufliciently to let the mounting snap in the channel over the rib 9 and in removing this sash, the mounting is likewise compressed sufficiently to permit it to snap over the rib 9. This rib 9 is merely high enough to prevent unintentional displacement of the sash adjacent the fixed side of the channel 4, whenthe other sash, which is adjacent the removable side 5, is demounted.

In the construction shown in Figure 2, when the removable side 5 of the outside frame 3 is clamped by means of the screws 8, the mountings 2 of the double sash are compressed against each other and toward the fixed side of the channel 4 and the removable side 5 compressed against the adjacent mounting 2. This compression force also compresses the sides of the grooves of the mountings on the margins of the glass panes I.

v In the form shown in Figure 5, the channel III of the outside frame 30 is formed with a rib or lip on the side thereof adjacent the removable side 50, corresponding to the rib 9 of Figure 2, to prevent inadvertent displacement of the single sash.

The means for dehydrating the air in the space between the two glass panes I, which space is sealed by the mountings 2, compressed against each other, consists of a flattened .tube l0 extending between the mountings 2 and opening at one end into said space and at its other end into a chamber l I in which a moistureabsorbing material is located, this being usually what is known as activated alumina. The chamber has a detachable cap or plug l2 opening through the face of the outside frame 3. The cap permits the moisture absorbing material, which is usually in the form of a plug or cartridge, to be removed and replaced. These chambers II and tubes ID are preferably located at one or more corners of the sash. The tube l0 extends between the mountings 2 at the rounding corners.

As the window openings in the body are usually rectangular, the outside window frame 3 is rectangular and the exterior corners square, and for convenience, the chambers II are located in the square portions of the outside frame beyond the rounding corners of the bottom of the channel 4 of the outside or window frame 3. When the mountings 2 are compressed against each other by the clamping action of the movable side 50f the channel 4, the mountings 2 distort to conform to the contour of the flattened tube 10 and snugly fit around the flattened tube l 0.

A sash either single or double of this construction is extremely economical to manufacture, readily placed into position and demounted, and the glass panes resiliently mounted and amply protected against shocks and strains. Owing-to the resilient frame of rubber, no sash frame of wood or metal is necessary, and hence a glass pane of maximum area may be installed in a window opening of a given size.
